BAK has added another hard roll-up tonneau cover to its already impressive array of products: The Revolver X4s. Like other Revolver covers, the X4s consists of interlocking aluminum slats, which are locked into place when the cover is shut thanks to BAK’s patented rotational locking rails. Once you open the cover, you’ll notice some distinguishing features. The clamps and the underside of the cover have been powder-coated matte black to create a nearly 100 percent black finish. Roll the truck bed cover toward your bulkhead and fasten it in place with the enhanced buckle and strap system when you need to access your gear or drive with tall cargo.

The BAK Revolver X4s is covered with heavy-duty vinyl to give your truck bed excellent weather resistance and provide a smooth, seamless look. When you need to open the cover, a simple string latch allows you to open and operate the cover with one hand. Closing the cover automatically engages the slam latch and rotational rails to provide ample security for your truck bed. Installation is easy using basic hand tools and you can have the cover out of the box and on your truck in less than an hour.

Keep rain and prying eyes out of your truck bed with the BAK Revolver X4s.
